Great looking setup. Seems like a great start. Are those hair algae spreading? It's common to have brown algae (diatom) at the early on stage, but you want to keep the green hair algae away as much as possible. What type of water are you using?
While I wait for the tank to clear, I thought I'd share my wish list for the fish I'd like to put in the tank. Comments and suggestions are welcomed!
Here's what I'd like, in order of addition:
Algea attack pack standard for 75g from drsfostersmith
3-4 blue/green chromis
2 Ocellaris clownfish
1 Lawnmower or one-spot blenny
1 Coral Beauty Angelfish
1 Saddle Valentini Puffer
1 Yellow Tang
Concerns:
Firstly, I'd be adding the fish very slowly over a long period of time. Especially after the blenny was added, I'd want to make sure the tank is well established before moving on to the rest of the fish.
Would this be an overcrouded tank?
